Set your dial frequency to 1.9KHz below the stated frequencies and keep the radio on USB. You can get this signal from a simple Grundig handheld radio with a nice long wire antenna and feed the speaker output right into your iDevice.

If you don't have access to a radio, I am open to experimenting via Skype or Google+ with you if you'd like me to tune my receiver to these frequencies and feed you the audio remotely. It could be a cool group demonstration on a G+ Hangout.

I've experimented with these transmissions and it's really hit or miss depending on the time of day, frequency selection and daily noise level. It makes for an interesting experiment, but I prefer to get my weather by voice broadcast, satellite or even HF email. It's not so frustrating as when the signal starts to fade on your wefax picture!
